HINGE.

SPECIFICATION forming part of Letters Patent No. 622,784, dated April 11, 1899.

Application filed April 4, 1898. Serial No. 676,397. (No model.)

To all whom it may concern:

Be it known that I, CARL ALBERT RoEPKE, a subject of the Emperor ofGermany, residing at Manchester, in the county of Lancaster, England,have invented new and useful Improvements in Hinges, (for which I haveobtained provisional protection in Great Britain, No. 20,713, bearingdate September 9, 1897,) of which the following is a specification.

My invention relates to improvements in hinge-fastenings fortune-sheets, jacquard cards, belting, writing-cases, doors, and thelike, and has for its object to so form the said fastenings that theyare extremely simple in construction, can be very easily and quicklyopened, and are very secure when closed. I attain this object bythe-device illustrated in the accompanying drawings as applied to atune-sheet, jacquard-card, machine-belt, or the like, and in which-Figures 1 and 3 are elevations and Figs. 2 and 4 sectional end Views,Figs. 1 and 2 of the fastening closed, and' Figs. 3 and 4 when open.

Similar letters refer to similar parts throughout the several views.

Referring to the figures generally, my improved fastening consists oftwo plates at and b, a of which is formed at the side with two eyes a a,which are at a suitable distance apart from each other, and the otherplate 1) with one eye 1), formed in hook fashion, open at its innerside. The said two eyes are fitted or formed with a pin 0, adapted toreceive the eye I) of the other plate I), which is hooked onto the pin 0when it is desired to close the fastening, as shown in Figs. 1 and 2.

In order to prevent the plateb becoming unhooked from the plate a, atongue at is pivoted to the plate b, the inner end of which is adaptedto enter the open side of its eye I) and bear against the pin 0 of theother plate (I, thus locking the two plates securely to-.

What I claim as my invention, and desire to secure by Letters Patent, is

In a hinge-fastening for tune-sheets, jacquard-cards,belting,writing-cases, doors and the like, the combination of two platesto and b, a of which is formed with two eyes a, a carrying a pin cand bof which a hookshaped eye 1) adapted to engage the pin 0, and a tongueat pivoted to the plate band having its end adapted to swing laterallyinto the eye b on the arc of a circle and parallel with the surface ofthe plate Z), all substantially as set forth.

In testimony whereof I have hereunto set my hand, in presence of twowitnesses, February 25, 1898.

CARL ALBERT ROEPKE.
